In 1962, American missionaries from New Tribes Mission International came to visit a village
deep in the forest called Nansiakan to survey possible area for ministry.

These were their names:

1. Dell Schultze

2. Byrd Brunemeier

3. Lee German

4. Bob Gustafson

Some time passed, three missionary couples came to the Kalanguya people. They were Sang and
Frances Boone, John and Lynne Eaton, and Gonzalo and Rose Tigo. When they came, they told
the people that they came to preach the Word of God.

1964-1965

In 1964, Sang Boone and his wife, came to Nansiakan and they lived in a house of one of the
villagers named Lugaman. They started teaching the Word of God in English and interpreted to
Kalanguya by one among the few of the Kalanguyas who can understand a bit English. During
that time, Sang Boone goes to rituals and tribal ceremonies and found out that it is against
the Word of God. Aside from teaching the Word, the missionaries also started giving
medicines and treating simple illnesses of the people.

1966

American missionaries Robert and Judith Ambrosius arrived in the Kalanguya village and
started working with the Kalanguya people in the Spring of 1967.

1967-1969

Bob Ambrosius started the Linguistic Analysis of the Kalanguya language. He started building
the Pedagogical Grammar to aid in the learning of the language by the other missionaries.
After which, he wrote a Kalanguya Language Course, Three Primers Translation and started
teaching the Kalanguya people to read and write their own language.

In 1969, Robert and Janice Bagley from NTM Australia came to Nansiakan

1968 - 1971

In 1968, Sang Boone went back to the USA and came back to Nansiakan in 1969 and continued
teaching the Word to the Kalanguya until 1971. In 1971, they left Nansiakan and went to
another village called Kamandag and lived there.

In 1970, Bob Ambrosius begun a Bible Study in Acab, a village 2 hours hike from Nansiakan
then Bob Bagley went in and continued the teaching ad lived there. Bob and Judy Ambrosius
then went to Paniki ni 1971 and Angel and Thelma de la Cruz came and joined them there.

1972

Bob Ambrosius continued translating the New Testament into Kalanguya beginning with the 4
Gospels and that four books were used by the other missionaries who teaches the Word of God.
There were Kalanguyas who served as language helpers to Bob. They were Federico "Pollang"
Malcat, Dionisio "Buhyag" Abansi, and other Kalanguya who now believed in Jesus Christ.

As the years went by, many Kalanguyas came to know and commit their lives to the Lord Jesus
and so a General Conference was held each year going from station to station: Oliweg where
Angel and Thelma de la Cruz were, in Acab where Robert and Janice Bagley resided, and in
Nansiakan where Robert and Judy Ambrosius continued teaching the people and translating the
NT into Kalanguya.

1975

The believers chose church elders then in 1982, deacons were also chosen to help the elders.

1977

In October 1977, Lynn Burgraff and Sherri Weygan arrived in Nansiakan and they were the ones
who taught the women and the children. They also started teaching Bible Studies to students
in the nearby high school.

1983

The New Testament in Kalanguya was finished and was dedicated in November of the same year.
During that time, many people bought the Kalanguya NT and as a result many Kalanguyas had
committed their lives to God.

1987

Thelma de la Cruz led in organizing the Young people and in the years that came and went,
the leadership of the YP assisted by the missionaries held their annual Youth Camp on a
December month. Youth Fellowships were also started in each village and many youth were
being led to Christ.

In the same year, 1987, the Missionaries had to evacuate their villages due to insurgencies
which were a danger to them. So in November 17th, 1987, Bob Ambrosius called the Kalanguya
believers to the NTM station in Aritao, Nueva Vizcaya who can teach the Word and mentored
them. By God’s grace, the Kalanguya believers had even increased in number during
those trying years and absence of missionaries. They had learned to really depend on God and
not on their missionaries.

In the year 2000, the revision of the NT was started and was published and dedicated in May
of 2001.

In 2002, the language helper who assisted Bob and Judy Ambrsius in the revision of the NT
committed to undergo Bible Translation training and do Old Testament translation into
Kalanguya. With the support of the Ambrosiuses, SIL and NPMTTA, and the Kalanguya churches,
the Old Testament is on its way to the finish, with only Psalms, Isaiah, and Song of Songs
in the drafting phase.

Books that were already consultant checked but are yet to be published are Exodus,
Leviticus, 1&2 Kings, Job, Ecclesiastes, Lamentations, and Habakkuk.

Books that are ready for checking are Numbers, Ezekiel.

Books that are still being drafted or under intermediate team checks are Deuteronomy,
1&2Chronicles, Psalms, Song of Songs, and Isaiah. The Kalanguya Translation team hopes
to finish the translation in 2015, and do a revision of the whole NT and OT, and have the
two published in one single book by the end of 2015.
